VASA Vanadium-Alloy Membrane for Ultra-High-Purity Hydrogen Purification
Non-palladium hydrogen-selective membrane module using a proprietary vanadium superalloy (VASA) to achieve >99.9999% H2 purity at lower material cost than conventional Pd-alloy membranes. The VASA module is designed for compact, low-maintenance purification systems targeting semiconductor fabs, hydrogen infrastructure, and medical applications.
Ultra-high-purity hydrogen (>99.9999%) is required for advanced semiconductor manufacturing (2 nm node, power devices), fuel-cell vehicles (H2 stations), and medical uses, but conventional Pd-alloy membrane purifiers are expensive due to palladium cost (~5,000/kg) and supply constraints. Vanadium is ~1/100th the cost with comparable theoretical H2 selectivity. However, vanadium membranes have historically suffered from hydrogen embrittlement and oxidation. UHP's VASA alloy formulation and module design claim to solve these durability issues.
PerovsJet inkjet coating system for perovskite solar cell R&D
A compact R&D inkjet coating platform purpose-built for perovskite layer deposition, using a glass/Teflon single-nozzle head that resists aggressive solvents (DMF, NMP) and requires under 0.5 mL of ink per evaluation cycle.
Perovskite R&D labs struggle to evaluate ink formulations at small scale because production slot-die coaters require large ink volumes and commercial inkjet printers lack solvent resistance for perovskite precursors. PerovsJet bridges the gap with 0.5 mL minimum ink volume and full chemical resistance.
Lithium-Selective Adsorbent for Direct Lithium Extraction (DLE)
A proprietary lithium-selective adsorbent material and associated concentration process that recovers high-purity lithium from salt-lake brine, geothermal water, seawater, and spent LIB black mass, requiring only pure water for elution.
Conventional lithium recovery from brine requires large solar evaporation ponds (months to years, weather-dependent, high water loss) or solvent extraction with chemical-intensive processes. This adsorbent enables selective lithium capture in a compact DLE process with no added chemicals for elution.
One-Stop TGV Glass Core Substrate Processing Service
End-to-end contract manufacturing service for TGV (Through Glass Via) glass core substrates, covering glass procurement, laser drilling, metallization, copper plating, polishing, dicing, and inspection in a single workflow using LPKF LIDE technology.

A compact femtosecond laser processing machine with proprietary GHz Pulse Injection Technology that forms TGV holes in glass directly via laser ablation without special optics or post-etching, achieving aspect ratios up to 240:1 in thin glass.
The complexity and cost of conventional TGV formation that requires laser modification + wet etching (multi-step, wet chemistry, environmental waste). Simpler direct laser drilling could reduce the process chain and eliminate chemical handling.
Rare-earth-free iron nitride (Fe16N2) nanocomposite magnet material
MAGesty series permanent magnet material composed of iron (Fe) and nitrogen (N) only — zero rare-earth content — synthesized as high-purity Fe16N2 powder suitable for bonded and compression-molded magnet production.
Eliminates supply-chain and price volatility risk from rare-earth elements (Nd, Dy, Tb) by creating a permanent magnet from iron and nitrogen, the most abundant elements, while targeting magnetic performance comparable to NdFeB magnets.
End-to-end CFRP/GFRP composite development from custom resin formulation to integrated assembly
60-year track record of full-spectrum CFRP product creation: in-house thermoset resin formulation, structural design and FEM analysis, mold fabrication, autoclave and filament-winding molding, 5-axis machining, coating, and system-level integration. Supports volume from single prototypes to 10,000+ units/month.
Overseas buyers of precision CFRP components — especially for semiconductor equipment, wind energy, and medical devices — typically must coordinate separately with a resin formulator, a design house, a molder, and a machinist. This fragmented supply chain multiplies qualification cost, lead time, and IP exposure risk.
Custom thermoset resin formulation for specialty composite applications
In-house development of custom epoxy, phenolic, and other thermoset resin systems tailored to specific application requirements — flame retardancy, heat resistance, chemical resistance, fast cure, or special surface appearance — integrated with CFRP/GFRP molding at production scale.
Standard prepreg systems from major suppliers (Toray, Hexcel) are optimized for aerospace structural properties but do not address application-specific constraints like flame/smoke/toxicity for public transit, chemical resistance for semiconductor wet processes, or fast-cure cycles for high-volume consumer-electronics production. Customers requiring specialty resin properties must either develop them in-house or work with multiple suppliers.
Silica White — Volcanic Glass Micro-Powder Concrete Admixture
A natural pozzolan micro-powder (volcanic glass ground to 3–4× cement fineness) that replaces a portion of Portland cement in concrete, reducing clinker factor while improving durability (waterproofing, chloride resistance, freeze-thaw resistance, ASR suppression). JIS A 6209 certified and JIS A 5308 listed. NETIS registered.
Reducing the clinker factor in concrete without sacrificing strength or durability is the primary lever for cutting construction embodied carbon, but supplementary cementitious materials (fly ash, slag, silica fume) face supply constraints and regional availability limits. Silica White offers a natural-pozzolan alternative sourced from domestic volcanic deposits.
CO₂-Nomicom — Carbonated Recycled Crushed Stone Aggregate
Recycled crushed stone aggregate from concrete demolition waste that fixes CO₂ through accelerated carbonation during processing. Used as road base, backfill, and subbase material. NETIS registered. Produced at multiple plants in Kanto region with combined capacity >2,000 t/day.
Construction demolition waste (concrete-ga ra) constitutes a major waste stream, and conventional recycling produces aggregate that still has a net carbon footprint from crushing and transport. CO₂-Nomicom converts the calcium-rich cement paste fraction into a CO₂ sink via accelerated carbonation, producing a carbon-negative recycled aggregate that can replace virgin crushed stone in civil engineering applications.
Amine-containing gel CO2 solid absorbent for low-cost capture from humid gas streams
A solid absorbent technology using amine-containing gel particles that captures CO2 efficiently from humid exhaust gas or ambient air without pre-drying, with weaker CO2 bonding enabling low-energy desorption.
Conventional amine solution scrubbing requires high energy for regeneration, equipment corrosion management, and pre-drying of gas streams. This solid absorbent operates efficiently under high relative humidity without pre-drying, and its weaker CO2 bond enables desorption at lower temperature, reducing total capture energy and cost.
Modular PEM water electrolysis stack for on-site hydrogen generation
Solid polymer electrolyte (SPE) water electrolysis stacks producing 70–1000+ Nml/min of hydrogen from pure water, scalable by cell count, operating at up to 0.9 MPa with compact footprint.
Provides compact, on-site hydrogen generation without alkaline electrolyte handling, enabling direct coupling with renewable power sources for green hydrogen production at laboratory, industrial, or mobility scales.
Ultra-thin composite copper foil for lithium-ion battery anode current collectors
PET film (6µm) base with copper plating (~1µm per side) achieving 4µm total thickness, half the weight, and one-quarter the copper consumption of conventional rolled copper foil, enabling lighter, more resource-efficient battery cells.
Conventional rolled copper foil for Li-ion battery anodes is limited to ~8µm minimum thickness before handling becomes impractical (tearing, wrinkling). Thinner foil could reduce battery weight and material cost, but thin copper alone is too fragile. Teikoku Ion's composite approach uses a polymer film substrate for mechanical strength while plating ultra-thin copper layers for conductivity, breaking the thickness barrier.
PowerBinder natural-polymer water-based electrode binder for sustainable battery manufacturing
Alginate/gelatin/chitosan-based water-processable binders replacing NMP-solvent PVDF systems for lithium-ion battery cathodes, enabling safer, lower-cost, environmentally friendly electrode manufacturing.
Conventional Li-ion battery cathode manufacturing uses PVDF binder dissolved in NMP (N-methyl-2-pyrrolidone), a toxic, flammable organic solvent requiring expensive solvent recovery systems and posing worker safety and environmental risks. PowerBinder enables water-based cathode slurry processing, eliminating NMP entirely.
High-precision laser patterning system for roll-to-roll perovskite solar module manufacturing
Laser patterning system achieving 20µm minimum processing width with patented stretch-compensation and contour-following correction, designed for perovskite solar cell dead-zone minimization and roll-to-roll compatibility.
Perovskite solar module manufacturing requires P1/P2/P3 patterning of transparent electrode, charge transport, and perovskite layers with micron precision across large areas. Substrate thermal expansion and layer shrinkage during processing cause misalignment, reducing active area. NITTOKU KYOTO's patented (JP5329505) stretch-compensation and contour-following technology enables <20µm dead-zone patterning, maximizing module efficiency in roll-to-roll production.

Scalable formation of dense vertical interconnects in large glass panels for cost-effective glass-core substrates used in co-packaged optics and high-density AI packaging.
Through-Glass Via Wafer Processing for 3D WLP and RF Applications
Precision TGV formation on borosilicate/alkali-free glass wafers (≤φ200mm) enabling hermetic vertical interconnects with low stray capacitance and high-frequency performance.
Conventional TSV or organic substrates suffer from higher parasitic capacitance, thermal mismatch, or outgassing in miniaturized RF/MEMS and 3D packaged devices for AI edge or sensor modules.
Large-Format Through-Glass Via Fabrication via Chemical Etching
Chemical etching process for high-aspect-ratio TGVs on large glass panels (up to 730x920mm) with fine vias (φ20μm–φ200μm) and integrated copper plating for 2.5D/3D interposers.
Wafer-scale TGV limits panel-level manufacturing economics and throughput for high-volume advanced packaging in AI servers or high-density interconnects; organic cores lack the flatness and low-loss benefits of glass.
Zeolite-based CO2 Adsorbent for Direct Air Capture
Innovative zeolite adsorbent optimized for low-energy desorption in modular DAC systems, leveraging University of Tokyo synthesis expertise.
High energy penalty and cost of conventional DAC sorbents for capturing dilute atmospheric CO2; need for materials enabling simpler regeneration without high heat.
Fe-Cr-Co (FCC) Cast & Rolled Rare-Earth-Free Permanent Magnets
Japan's only commercially available Fe-Cr-Co permanent magnets — a nickel-free, rare-earth-free alternative to Alnico and NdFeB — available in both cast block and rolled sheet/foil forms for sensor, stepper motor, solenoid, and magnetic clamp applications.
Manufacturers of sensors, stepping motors, and magnetic couplings face volatile pricing and supply risk for rare-earth magnets (NdFeB, SmCo). Ferrite magnets offer low cost but also low magnetic performance. Alnico magnets avoid rare earths but are expensive (high Ni and Co content) and cannot be rolled into thin shapes. Fe-Cr-Co magnets fill the gap: zero rare earths, zero nickel, higher Br than ferrite, and rollable into sheet as thin as ~0.5 mm.
Copper Paste for Electrode and Wiring Formation
Mass-producible copper paste enabling low-resistance electrodes and wiring as direct substitute for silver paste in photovoltaic and electronic devices.
High material cost and supply constraints of silver paste in electrode formation for solar cells and battery-related electronics.
